I have a new tractor, opened the air box and found a Donaldson air filter.
Donaldson is a major supplier of air filters to industries. In todays world, you never know where an item is going to be manufactured.
I’ve only bought a aftermarket filter once, a Kumar brothers air filter and it was a pos, it didn’t fit tight on the inner filter at all and would have let dirt right in the intake. Threw it away.
I will just always buy them at the dealer and assume I’m all good.
I purchased an air filter form Kumar Brothers, and it fits just fine, including with my inner filter. If you had a problem with your Kubota, would you complain to the dealer, or would you just throw it away? Did you ever consider that the one filter that you received was defective, and the seller would have just replaced it with another, that would fit properly? Defects happen all the time, and sometimes they get out into the market, and only then is is discovered. I had a new screwdriver shaft installed into my Snap On screwdriver last week, and the first time I used it, the tip snapped just like the one that was a year old. The Snap On dealer told me that occasionally, they get a bad batch that wasn't properly tempered, and they are brittle. He replaced it again, and this one works like it was intended to. If the world was perfect, then there would be no need for tools in your garage, or spare parts on the dealers shelf. That is the wonderful thing about the internet, there is always someone complaining about something that happened to only them, and they condemn the entire company for their problems. This is only the second post that I have read this morning, and 2 people are bitching about quality of a part or Kubota manufactured a part that was 18 years old, and failed, and that Kubota should replace it at their expense. What a bunch of whiners that can only see things as black and white. I'll bet that when they went to school, that their pencils didn't have an eraser at the end, because they never made a mistake, and were perfect little angels that could do no wrong!
